FIG. 6 is an isometric view of the top left of a second embodiment of the light bulb.

FIG. 7 is an elevation view of the right side of the second embodiment of the light bulb.

FIG. 8 is a plan view of the top of the second embodiment of the light bulb.

FIG. 9 is a plan view of the bottom of the second embodiment of the light bulb.

FIG. 10 is an isometric view of the bottom right of the second embodiment of the light bulb.

FIG. 11 is an isometric view of the top left of a third embodiment of the light bulb.

FIG. 12 is an elevation view of the right side of the third embodiment of the light bulb.

FIG. 13 is a plan view of the top of the third embodiment of the light bulb.

FIG. 14 is a plan view of the bottom of the third embodiment of the light bulb; and,

FIG. 15 is an isometric view of the bottom right of the third embodiment of the light bulb.

The designations of the views below as top, bottom, right side, front, and rear are for ease of discussion only and are not intended to limit the light bulb to one particular orientation. The drawings illustrated in FIGS. 1-15 are not necessarily drawn to the same scale, and any change in scale between different views is not intended to limit the light bulb to a particular size. The light bulb is radially symmetric, so only one elevation side view is shown. 

CLAIM We claim the ornamental design for a light bulb, as shown and described.
